This article is about calculating melee damage output. Melee damage is affected by the Equipment used, prayer, skill boosts and the monster being attacked.

There are various methods by which players can increase their potential Melee damage. The effects of most equipped items can be seen in the stats window (labelled as Stab, Slash, Crush and Melee Strength).

Calculating your melee damage output[edit | edit source]

Step one: Calculate the effective strength level[edit | edit source]

Effective level is affected by your current strength level multiplied by prayers used and skill level boosts.

To calculate your effective strength level:

  1. (Strength level + Strength level boost) * prayer bonus
  2. Round down to nearest integer
  3. +3 if using the aggressive attack style, +1 if using controlled
  4. +8
  5. Multiply by 1.1 if wearing full melee void
  6. Round down to nearest integer

Step two: Calculate the maximum hit[edit | edit source]

The maximum hit is is the largest hit you can possibly do with the current setup. It can be tested by using the Combat Dummy in a Player Owned House.

To calculate your maximum hit:

  1. Effective strength level + 0.5
  2. Multiply by (Equipment Melee Strength + 64)
  3. Divide by 640
  4. Round down to nearest integer
  5. Multiply by gear bonus
  6. Round down to nearest integer

The Equipment Melee Strength can be found in the Equipment Stats window under 'Other bonuses'.

If slaying monsters on task while wearing a black mask or slayer helm, gear bonus is 7/6.

If killing undead monsters while wearing a salve amulet, gear bonus is 7/6, or 1.2 if using salve amulet (e) or (ei).

Note that these two bonuses DO NOT stack.

Step three: Calculate the effective attack level[edit | edit source]

Effective level is affected by your current attack level multiplied by prayers used and skill level boosts. To calculate your effective attack level:

  1. (Attack level + Attack level boost) * prayer bonus
  2. Round down to nearest integer
  3. +3 if using the accurate attack style, +1 if using controlled
  4. +8
  5. Multiply by 1.1 if wearing void
  6. Round down to nearest integer

Step four: Calculate the Attack roll[edit | edit source]

  1. Effective attack level * (Equipment Attack bonus + 64)
  2. Multiply by gear bonus
  3. Round down to nearest integer

The Equipment Attack bonus can be found in the Equipment Stats window, and is labelled Stab, Slash, Crush. Use the value of whichever attack type you are using.

Gear bonus is the same as in Step 2.

Step five: Calculate the Defence roll[edit | edit source]

  1. (Target's Defence + 9) * (Target's style defence + 64)

Target's Defence is denoted by a shield icon on the target's wiki page.

Target's style defence refers to it's stab, slash or crush defence, depending on the attack type used.

Step six: Calculate the hit chance[edit | edit source]

If Attack Roll > Defence roll:

Else

Step seven: Calculate the melee damage output[edit | edit source]

To calculate the Damage Per Second, divide the Damage Per hit by the attack speed of the weapon in seconds.
